problem #3

RX 350

  • 5,600 miles


Dynamic speed control randomly (twice) has lost settings & control. Setting it at 60, car increased speed to 85, and ignored car in front of me, almost causing a crash. Lexus has not followed up with me on this. Voice recognition often functions incorrectly resulting in distracted driving, and has almost resulted in me driving out of my lane or off the road several times. Example: Ask it for directions to palo alto medical foundation: Result; gives me a list of South american restaurants. Contacted Lexus about this. Only response - take it to a dealer. I have an appt with one July 11. No documentation available. Self repair attempts: Disconnected the car battery for 30 seconds to reset the system and reprogrammed all settings available. Result: No change. Summary: With regard to the cruise control; someone could get killed from this!
